SPECIFICATION forming part of'Letters Patent No. r791,858, dated June 6,1905.

Application iled June 11` 1904:. Serial No. 212,138.

To @ZZ whom t may concern,.-

Beit known that I, MAUDE E. BAILEY, acitizen of the United States,residing at Cromwell, in the county of Middlesex and State ofConnecticut, have invented certain new and useful Improvements inCartridges, of which the following is a specification.

This invention is an improvement in cartridges, and relates moreespecially to the class of paper-tube cartridges.

The object of the invention is to provide a simple and inexpensivebreech construction for a paper-tube cartridge in which the paper tubeand metal cap are intimately and strongly connected and in such manneras to reinforce the breech.

The invention contemplates the employment of a metal lining struck up toprovide extensions that are bent inward upon themselves to formenlargements or lugs adapted to be embedded in the paper tube andintimately connect the same with said lining, such connection beingtirmly maintained by means of the usual paper wad or breech-piece, allas will be hereinafter particularly described, and the novel featuresmore specifically pointed out in the appended claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a sectional view of a paper-tube cartridge constructed inaccordance with my invention. Fig. 2 is a detail sectional View of thecap and metal lining connected together by the usual rim-ange. Fig. 3 isa detail view of the metal lining, illustrating the manner of making thesame.

Like letters of reference indicate like parts in all the gures of thedrawings.

Referring to said drawings, the letter A designates the metal cap; B,the metal lining; C, the paper tube, and D the usual breechpiece, whichis inserted to connect the parts and further reinforce the breech.

In carrying out my invention the metal lining B is struck up or cuppedfrom a square piece of sheet metal, whereby four pointed extensions areformed, as shown in dotted lines, Fig. 3, and these extensions are bentinward upon themselves to provide enlargements or lugs b', disposed atthe inner side of the lining and V-shaped. This metal lining is insertedin the cap A, and both are flanged outward, as in Figs. 1 and 2, toprovide the usual rim-flange aand also connect said parts together. Whenthus connected, the cap is provided with a lining at the breech of thecartridge, and the enlargements or lugs formed on said lining arepeculiarly adapted to engage and securely hold the paper tube to thecap. In applying the paper tube one end of the same is slightly reducedand inserted in the connected cap and lining, after which thebreech-piece or wad D is inserted in the paper tube and compressed bythe usual method, which latter operation will clamp the tube betweensaid breech-piece and lining and cause the V-shaped enlargements or lugso of the lining to be embedded in the paper tube and such engagementmaintained by the Wad or breech-piece. The paper tube may be eitherplain at its inner end, as illustrated in Fig. 1 of the drawings, orsaid inner end may be crimped inward, as is usual.

In the usual manner of connecting the paper tube and the metal cap, thelatter either with or Without a lining, the breech-piece alone has beenrelied upon to provide the required connection of the parts; but such aconnection relying solely upon frictional engagement is not suiiicient,inasmuch as it Will readily yield when force is applied in removing ajammed cartridge from a firearm and results in a separation of the capfrom the tube. This is more often the case when an attempt is made toremove the shell by turning the same, such operation usually resultingin turning the cap upon the tube, and thereby loosening the connection,so that the cap alone is removed. Therefore by providing a metal cap ofa paper-tube cartridge With a metal lining having a series of lugs orenlargements struck therefrom and embedded in the tube by the expansionof the breechpiece in compressing the latter in the shell the said papertube is intimately connected to the parts, and the connection willwithstand both longitudinal and lateral strain, thus insuring aWithdrawal of all the parts of the IOO The manner of making up the metallining by forming the lugs from the stock in the manner describedprovides a cheap construction.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A paper-tube cartridge, comprising a metal cap, a lining securedtherein and provided with inwardly-projecting lugs or enlargements, apaper tube inserted in said lining, and a breech-piece expanded to embedthe lugs or enlargements of the lining into the tube.'

2. A paper-tube cartridge, comprising a metal cap, a metal liningsecured therein and provided with inwardly-projecting lugs orenlargements, a paper tube inserted in said lining, and means expandingthe tube to embed the aforesaid lugs or enlargements of the lin- A ingtherein.

3. In a paper-tube cartridge, the combination with the metal cap, of ametal lining secured thereto by the usual rim-Bange, and inwardlyprojecting lugs or enlargements formed on said metal lining; togetherwith a paper tube inserted in the lining, and means for expanding thetube to embed the lugs or enlargements therein.

4. In a paper-tube cartridge, the combination with the metal cap, of asheet-metal lining having portions of the sides thereof bent upon suchsides to form lugs or projections, a paper tube, and aibreech-pieceexpanding the tube so as to embed the lugs or projections therein.

5. In a paper-tube cartridge, the combination with the metal cap, of ametal lining secured therein and having lugs or projections formed byextensions of the sides bent inward upon the latter, a paper tubeinserted in the lining, and a breech-piece expanded to embed the lugs orprojections into the paper tube.

6. In a paper-'tube cartridge, the combination with the metal cap,ofainetal lining struck or cupped up from a square piece of sheet metal toprovide pointed extensions which latter are bent inward upon themselvesto form V-shaped projections or lugs ZJ', apaper tube inserted in saidmetal lining,and a breechpiece inserted in the paper tube and expandedto embed the lugs or projections into the paper tube to intimatelyconnect the parts.

7. In a paper-tube cartridge, a metal piece for connecting the papertube, said metal piece having inwardly-projecting lugs on the side wallsthereof, which lugs are embedded in the paper tube; combined with thebreech-piece expanding the paper tube against said lugs, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
